Customer Reviews (4.4 / 5 · 5 reviews)

Adam ★★★★★

I needed serious lag bolts for a timber frame project and these didn't disappoint — the 5/8” diameter threads bit into the wood cleanly with no stripping. Even after a few weeks of wet weather, the 18/8 stainless surface shows zero rust spots.

Robert ★★★★★

My deck ledger board needed a serious anchor and these 18/8 stainless steel lags went in clean without a single one snapping. The 5/8" x 16" length gave me the bite I needed into the framing, and the hex head grabbed my socket perfectly. Weather won't touch these things for years.

Riley P. ★★★★★

Finally, some lag screws that don't strip or corrode after a single season outside. These 18/8 stainless steel ones bit into the treated lumber perfectly and held solid—no wobble at all.
